I would suggest that you avoid using this scheme. This is the
DejaGnu style, and to be honest I think it is really confusing.
Instead, how about the following results:


The PASSED result means the test case result matched
the expected result. A FAILED result means the test
case result did not match the expected result. When
you see a result transition like:


It is clear that this is a regression.

Same goes for:


This is not the same as a FAILED since we would
want to take special note of a code path that
drops core. Along the same lines, we would want
to be informed of a transition like:


That is clearly not good. The other side of
the coin is a transition like:


It is clear that you just fixed a bug.
This approach is a lot easier to grasp IMHO.
